Effect Analysis of GPS Observation and Satellites Clock Bias Sample Rates on Convergence Behavior in PPP

摘要

Convergent time (CT) is one important aspect of GPS kinematic precise point positioning (PPP). There are many factors which affect performance, including the effect of different sample rates of observations and GPS satellite clock bias (SCB) (or satellite clock offset), different positioning accuracy on CT of kinematic PPP is discussed deeply in this paper, taking GPS observations from twelve stations in a GPS network from Shanghai, China, we analyzed the relationship between CT and sample rate, positioning accuracy and convergence behavior.
